While true, fossils are buried with plenty of clues that allow us to reconstruct their history. In , in Ethiopia’s Afar region, our research team discovered a rare fossil jawbone belonging to our genus, Homo. To solve the mystery of when this human ancestor lived on Earth, we looked to nearby volcanic ash layers for answers. Working in this part of Ethiopia is quite the adventure.
It is a region where 90 degrees Fahrenheit seems cool, dust is a given, water is not, and a normal daily commute includes racing ostriches and braking for camels as we forge paths through the desert. But, this barren and hostile landscape is one of the most important locations in the world for studying when and how early humans began walking upright, using tools and adapting to their changing environments.
Results from absolute dating methods will not be available from a laboratory for several weeks, and the paleontologist needs the information.
Examining the Fossil Record. Fossils are traces of organisms that lived in the past. When fossils are found, they are analyzed to determine the age of the fossil. The absolute age of the fossil can be determined though radiometric dating and determining the layer of rock in which the fossil was found. Older layers are found deeper within the earth than newer layers. The age and morphologies appearances of fossils can be used to place fossils in sequences that often show patterns of changes that have occurred over time.
This relationship can be depicted in an evolutionary tree, also known as a phylogenetic tree. There are two major hypotheses on how evolution takes place: gradualism and punctuated equlibrium. Gradualism suggest that organisms evolve through a process of slow and constant change. For instance, an organism that shows a fossil record of gradually increased size in small steps, or an organism that shows a gradual loss of a structure. Punctuated equilibrium suggests that species evolve very rapidly and then stay the same for a large period of time.
This rapid change is attributed to a mutation in a few essential genes.

Around the time that On the Origin of Species was published, Lord Kelvin authoritatively stated that the Earth was between 20 and million years old, a range still quoted today by many who deny evolution. As it was difficult to conceive of life’s diversity arising via natural selection and speciation in so short a span, the apparent young Earth formed a serious barrier to the plausibility of evolution’s capacity to generate the tree of life.
Huxley famously attacked Kelvin, saying that his calculations appeared accurate due to their internal precision, but were based on faulty underlying assumptions about the nature of physics . Garniss Curtis was born in San Rafael, California in
